The second volume of the Genshiken reboot follows the previous one not just in story, but in both my praise and complaints. The references to new anime creates something of a continuity error from the original time line, but it keeps in the spirit of the original and most of the jokes are so funny that I don't care (it may have been my sleep deprived mind, but reading the "Nice boat!" line at 4AM was hilarious).
We get to learn more about the newer characters in this volume, all are better developed than they were before, so this is the volume that will probably let you decided if you like the new cast (I personally miss the old characters, but their cameos make up for the lack of some of them).
Translation is great, and the index in the back is practically necessary for any reader. While I got a good portion of the jokes without it, Genshiken has always thrived on Anime in-jokes. If you were already a fan of the series, this should make you happy knowing that some things don't change.
All in all, I am completely satisfied with this second volume. While I miss the old cast, the new characters are interesting, and they take the series in a fun new direction while still being true to the original. Highly recommended.
As with all series like this, make sure you read the previous volumes before this one... including the original Genshiken series. While the reboot is pretty good in explaining things, I imagine it wouldn't be near as enjoyable without knowledge of what came before.
